“All I know at the moment is I’m doing these three [for the upcoming series three] and another three,” the star said at the South Bank Show Awards. He also mentioned that he “could get into trouble saying that.”

For fans of the show and Sherlock Holmes in general, this is fantastic news. The only question now is which (if any) stories from the Doyle canon will be next up. Last summer, Moffat revealed three words that will comprise the episodes for Sherlock season 3. But what of season 4? Shall we see adaptations of The Valley of Fear? “The Sussex Vampire”? Or perhaps one of the adventures they’ve already mentioned offhandedly, like “The Speckled Blonde”?
